Senior Architectural Systems marks its 30th anniversary

  • 29 Apr 2021

The end of the Cold War. The introduction of the ‘World Wide Web’. 1991 was a notable year for many reasons, but for Senior Architectural Systems, it marked the beginning of a successful journey to become the UK’s largest privately owned aluminium fenestration systems house.

This year, the company is celebrating its 30th anniversary of successful trading and its growth from humble beginnings in Bradford. 

From then, to now – the company stands strong at the forefront of the aluminium fenestration industry, with three branches nationwide.

As well as growing in size and turnover, Senior also invests heavily in the research and development of its product range. This allows the company to offer some of the most advanced aluminium window, door and curtain wall systems available. 

A pinnacle moment for the company came with the launch of the market-leading PURe® system. This has the potential to achieve exceptionally low U-values, receiving a UK patent in 2016. 

Senior has also grown its range of in-house services, including its own state of the art powder coating facility. It continues to embrace sustainable manufacturing techniques at its main manufacturing premises in Denaby, South Yorkshire.

Senior’s extensive product range, customer-service focus and the autonomous flexibility remains a key part of its identity as a UK-based and privately-owned systems house. All of which help the company stand out from its competitors and remain key to its future growth.


‘Seen it all’

Mark Wadsworth, Senior’s managing director, comments: “Like other companies that have been around since the early nineties, we have seen it all – recessions, booms, regulatory changes, our own MBO back in 2018, Brexit and even a global pandemic.

“We’ve been fortunate to have not only survived but to have thrived over the last 30 years, but we wouldn’t have been able to achieve any of this without the support of both our customers and our colleagues.

“We have a number of exciting developments in the pipeline and we are excited to continue our journey alongside our great team and supply chain partners.”

Senior projects

With a strong standing in the commercial sector, Senior products feature on a number of high-profile projects. The company’s versatile and slimline SF52 aluminium curtain wall, which was launched in 2015, has also become the company’s most popular and widely specified system and features on a number of buildings, including the new striking Danum Gallery, Library and Museum in Doncaster. This is just a few miles away from Senior’s Denaby HQ.

Senior has also embarked on several framework agreements with main contractors, resulting in numerous repeat-business contracts in both the education and health sectors.

Most recently, Senior received a supply chain award from main contractor Morgan Sindall, in recognition of its commitment to offering a consistently high and reliable level of service and support. 

Over the last few years, Senior has also been involving itself in the delivery of numerous Education Funding Agency (EFA) framework contracts, working closely with B&K to supply its thermally-efficient PURe® window system to schools across the country.

Enhancing its domestic market offering with the launch of the Ali FOLD patio door in 2017, Senior soon supported this by the development of an Ali VU, a stylish slimline aluminium windows system and Ali SLIDE patio door option.

Mark Wadsworth says that as a key supplier to the construction industry, Senior remained operational throughout the national lockdowns and are now in a ‘strong position’ to continue to develop its product range and service offering to meet future challenges.

“From putting procedures in place to reduce any potential disruption caused by Brexit to increasing capacity to meet demand and ‘future-proofing’ our already market-leading PURe® windows and doors to comply with the pending changes to Part L of the Building Regulations, we’re ready to take on whatever opportunities or challenges the future may hold,” he adds.
